NHTSA Complaint #11686976 — 2016 KIA SOUL

My 2016 Kia Soul is experiencing severe oil consumption, piston ring failure, and smoke from the exhaust. The vehicle is covered under Kia’s engine warranty extension (Product Improvement Campaign PI2002B and subsequent updates), which extends coverage to 15 years/150,000 miles on the engine short block/long block assembly. The dealership confirmed the failure is due to piston oil rings, but Kia America has denied warranty coverage, stating that because the rod bearing clearance test passed, the repair is not covered. This denial contradicts Kia’s own documentation, which defines the covered “short block assembly” as including pistons and piston rings, in addition to bearings and connecting rods. By refusing coverage, Kia is effectively narrowing the warranty in a way that leaves consumers unprotected, despite the campaign language. This issue raises a safety concern because excessive oil consumption and piston ring failure can lead to: Engine smoke and emissions problems, Sudden power loss, and Increased risk of engine failure while driving. I am requesting that NHTSA investigate Kia’s handling of piston ring and oil consumption failures under the engine warranty extension, as Kia appears to be limiting coverage only to rod bearing failures, despite covering the entire short/long block assembly on paper. Summary: VIN covered under PI2002B/KSDS update. Engine is consuming oil and smoking due to piston ring failure. Kia refuses coverage because rod bearings passed the clearance test. Piston rings are part of the short block, yet warranty is being denied. Safety issue due to risk of engine failure and increased emissions.
